The Environmental Sustainability major brings together the natural sciences, social sciences, and cutting-edge data tools to help students understand how the Earth works—and how we can care for it. Students explore everything from biodiversity, ecology, and climate processes to the forces that shape landscapes, oceans, and weather. Whether you’re studying the emergence of life, tracking severe storms, or examining how rivers, hazards, and resources evolve, you’ll gain a deep foundation in the interconnected systems that sustain our planet.
Beyond the physical sciences, the major also examines how people, places, and policies influence environmental outcomes. Courses in environmental economics, global food systems, sustainability planning, environmental writing, and the human dimensions of climate change give students the tools to create meaningful change in communities and organizations. With advanced options in GIS, remote sensing, restoration ecology, energy systems, and more, the major empowers students to tailor their path and prepare for careers across science, policy, communication, and sustainability practice. Explore the full list of offerings to see how the curriculum can fit your interests and goals.

Outline of the ES Bachelor of Science in Liberal Arts and Sciences
The ES program offers a unique combination of structure and flexibility not found in most programs at the University of Illinois. Since most students are not accustomed to the level of choice we offer in our majors, the ES program has professors ready to advise you on tailoring your degree.
One Concentration (18-22 hours)
- Society and Environment (SAE) OR
- Science of the Earth System (SES)
ES Introductory Core: Required Courses (10 hours)
- ESE 200: Earth's Physical Systems
- ENSU 300: Environmental Sustainability
- ESE 379: Intro to GIS Systems
ES Advanced Courses (18-24 hours)
- Six advanced courses from the approved list, four must be from the ESE or ENSU rubric.
Choose a Concentration
After studying cross-disciplinary introductory classes, ESES students choose to focus in one of two concentrations, depending on their developing interests.
- STAT 100 (3 hours)
- ECON 102 (3 hours)

ES Courses by level

ES Required Core, 10 Hours
Both of the courses below are required. ESE 200 is a general introduction to sustainability and is followed by the intermediate course ENSU 300. ESE/GGIS 379 introduces students to the software and practices for viewing data on a map in ArcGIS. Typically, ESE 200 is offered in the Fall semester, ENSU 300 is offered in the Spring semester, while ESE/GGIS 379 is available in both the Fall and Spring semesters.
- ESE 200: Earth Systems (3 hours)
- ENSU 300: Environmental Sustainability (3 hours)
- GGIS 379: Introduction to Geographic Information Systems (4 hours)
ES Advanced Courses, 18-24 Hours
A minimum of six (6) 300- and 400-level courses, from the approved list, are required. At least three of these five advanced courses must be listed or cross-listed as an ESE or ENSU course. Advanced courses will, in most circumstances, count toward the LAS requirement of 21 hours of 300- or 400-level courses overall, and 12 hours of 300- or 400-level courses in the major. It is strongly recommended that students complete the LAS requirement with 21 hours of 300- or 400-level courses related to the ESE curriculum. Please note that your DARS report will not show these requirements as being met until you complete a Major Plan of Study with your advisor.
Looking for hands-on experience in a class? Consider ESE 401: ESE Capstone. ESE 401 provides a pathway for students to earn course credit for a senior thesis or an internship experience. Make an appointment with Dr. Jonathan Tomkin to learn more about ESE 401.
